Dark Matter

暗物质照耀的可居星球

尽管暗物质本身不会被照亮,也没有温度,不会发热,但它们会发光!当然,它们并不发射可见光,而是发射伽玛射线。暗物质粒子间相互碰撞会有一定几率发生湮灭反应,转化成伽玛光子。对一些大型行星,这种伽玛光子可能足够多从而使行星上保持液态水,进而孕育生命。

Analysis of heavy neutrinos as a dark matter candidate

Abstract: Neutrinos heavier than $M_Z/2\sim 45$ GeV are not excluded by particle
physics data. Stable neutrinos heavier than this might contribute to the dark
